If there is someone blind here it is you, or at least you have some huge memory problems.
According to AMD Bulldozer was the right chip for the cloud, it was THE one. Still can't remember? Here is our friend John Fruehe talking to world + dog about how wonderful Bulldozer is to cloud servers:

What about this white paper here, called "Hybrid Hosting: Evolving the Cloud in 2011. How Superior Price/Performance Can Create a Business Advantage"

So, one year after, Bulldozer is not the right for for the cloud, ARM is the one. Oh, really? So Bulldozer wasn't that marketing, but strategy, or Bulldozer was marketing and with ARM they stopped joking and are now designing credible strategies? But what is AMD doing now? Is strategy to take a growth forecast from another company and put it in your slide as if you have the right product mix to grow with the market? Is strategy to call an event and to announce that in two years you will be shipping generic cores of an unproven technology on the server market?
Who is saying that ARM is the right solution for cloud servers? Who is saying that even if ARM becomes relevant on servers, that AMD servers will be relevant too? That's right, it is AMD executive team and its marketing department.
Btw, you should really take AMD "strategy" slides since 2005 and double check with reality. You'll have quite a few surprises I assure you.
